Key result
Cryptic promoter activation in CACNA1C exon 46 drives CCAT production independent of CaV1.2 expression.
Why the study?
The mechanisms by which the transcription factor CCAT is generated from the CACNA1C gene in neurons and myocytes are poorly understood.
Design
Molecular biology study investigating CACNA1C gene transcription

No immediate clinical implications; extends molecular understanding of Cav1.2 regulation in cellular models.
Gomez‐Ospina et al. (2013) studied this question. CACNA1C gene analysis was evaluated on Mechanism of CCAT generation. CCAT is produced by activation of a cryptic promoter in exon 46 of the CACNA1C gene, independent of CaV1.2 expression, demonstrating how exonic promoters contribute to mammalian genome complexity.
